I don't think a cork gasket would work Dave - because it has to go over the camshaft seal hump at one end and then turn almost 90 degrees on both sides. I'm pretty sure it was thickish cardboard, I'll check in the spares box today. If there was a rubber one (on the 740?) I'd buy one - it is an easy job but I don't want to be doing it every year.

I can't find a torque setting for the nuts in any of the books, the consensus seems to be: snug plus 1/4 turn. This chap did a very detailed write up (on a pretty simple job) and doesn't mention it either:

I've only ever seen paper type gaskets for the rocker cover.

Maybe i'm thinking of a different engine.

Bentley 6 3/4 haha, god they were horrible to fit. In the turbo R you had to dismantle the top of the engine to get the rocker covers off!

Readers may recall that the RB will qualify as an historic car, and therefore be exempt from VED, on 1 April this year (which will be nice). It became MoT exempt in October last year, its last MoT expired in January.

The DVLA (bless their cotton socks) wrote to me in January saying the tax would expire (I pay by monthly direct debit) at the end of February. I wondered how I would pay the tax for the final 2 months and wrote to DVLA to ask - without getting a sensible answer of course.

Well, the tax ran out, I kept using the RB - with a copy of my letter to DVLA in the glove box just in case the police stopped me (unlikely I know, but I would never knowingly break the law). I really didn't want to pay for another MoT as a matter of principle (I am absolutely certain the RB would pass with no problems) and I saw no reason why I should SORN the car for 2 months, but I didn't want to transgress.

Still confused by DVLA's lack of direction I thought I'd have a go at taxing the motor car again via DVLA's website - and much to my delight I found DVLA had a software fix for 40 year old cars that had not yet qualified for historic vehicle registration (but had not advertised that anywhere).

So, the answer is this (on the off chance that someone else should have to tax a car in the same unusual circumstances): wait for the old tax to expire (as mine did on 31 January), then fill in the tax application on the DVLA website as normal - an extra page will appear during the process saying words to the effect that 'DVLA recognised the car is over 40 years old and not liable for a MoT, so tick here if you promise your car has not been substantially modified and is roadworthy'... then pay the money (by monthly direct debit) and Robert is your mother's brother. Unfortunately I didn't take a screen shot of the extra page.

I was really impressed that the DVLA knew of the issue and had already fixed it, but I'd have been even happier if it had publicised it.

:-)

I was thinking more along the lines of the Ford Pinto engine, they used cork gaskets and they had a dovetail join in on the back end. The front end was wider to cope with going over the front cam bearings and was more or less a right angle where it levelled out onto the rest of the head :

You'll see what i mean in that listing. Had a quick look for Volvo ones, all appear to be paper so maybe a thicker paper one would work better. Might have to DIY though!

I was thinking that if I can't get a standard paper gasket to seal up properly on my 40 year old engine that I might have to make a thicker one myself.

I'll have a go at your first idea (loosening all the bolts and then tightening them all down again in order) this morn and see if that works first.

Good thinking - don't forget to check/clean the PCV system in case that's causing excess pressure too.

Just a thought on the cambox gasket: is the cambox lid true? Although the metal is substantial (unlike a certain other company's slant-4 of my acquaintance) might it be slightly distorted and in need of gentle "fettling"?

That all seems fine Dave, I blew it through from the flame trap and it is clear.
